Abstract
An endless belt includes a band-shaped belt main body made of a vulcanized rubber, and a coupling part that is made of a thermoplastic resin and is provided between both end parts of the belt main body, wherein the vulcanized rubber of the both end parts of the belt main body and the thermoplastic resin of the coupling part are chemically bonded to each other.

1-13. (canceled)
An endless belt, comprising:
- a band-shaped belt main body made of a vulcanized rubber;
- and
- a coupling part that is made of a thermoplastic resin and is provided between both end parts of the belt main body, wherein
- the vulcanized rubber of the both end parts of the belt main body and the thermoplastic resin of the coupling part are chemically bonded to each other.
1 more element
A band-shaped belt, comprising:
- a band-shaped belt main body made of a vulcanized rubber;
- a first coupling part that is made of a thermoplastic resin and is provided on a first end surface that is one end of the belt main body in a longitudinal direction to extend in the longitudinal direction of the belt main body;
- and
- a second coupling part that is made of a thermoplastic resin and is provided on a second end surface that is the other end of the belt main body in the longitudinal direction to extend in the longitudinal direction of the belt main body, wherein
- the vulcanized rubber of the first end surface and the thermoplastic resin of the first coupling part are chemically bonded to each other, and the vulcanized rubber of the second end surface and the thermoplastic resin of the second coupling part are chemically bonded to each other.
2 more elements
A method for manufacturing a band-shaped belt, comprising:
- a stacked body forming process of disposing a band-shaped thermoplastic resin sheet that is made of a thermoplastic resin and serves as a coupling part, and an unvulcanized rubber sheet that includes an unvulcanized rubber and a crosslinking agent covalently bonded to the unvulcanized rubber and the thermoplastic resin and serves as a belt main body on a mold surface in a state in which end parts are in contact with each other to obtain an unvulcanized stacked body;
- and
- a vulcanization-molding process of vulcanization-molding the unvulcanized stacked body.
